Eaton 9E UPS (40–60 kVA, 208/220V) Generation 3 Installation and Operation Manual P-164000302—Rev 1 www.eaton.com/powerquality 1-3
1.2 Options and Accessories
Contact an Eaton sales representative for information about the following options.
1.2.1 External Battery Cabinet Capability
External battery cabinet capability provides the ability to add Eaton 9E EBCs to the UPS system in addition to
the internal batteries. An internal UPS battery breaker and external battery terminal block are added, along with
other internal parts allowing the connection of up to two EBCs.
1.2.2 External Battery Cabinet
Battery backup protection with additional runtime can be provide by equipping the UPS system with up to two
External Battery Cabinets (EBCs) containing sealed lead-acid, maintenance-free batteries. The EBCs are
available with four or six battery strings. Only EBC capable UPS systems can utilize EBCs. The EBCs are housed
in single, free-standing cabinets designed for line-up-and-match installation, but may be installed separate from
the UPS cabinet. The recommended installation location for adjacent battery cabinets is on the right side of the
UPS cabinet.
1.2.3 Integrated Accessory Cabinet-Distribution
The Integrated Accessory Cabinet-Distribution (IAC-D) provides power distribution with a 42-pole distribution
panel and up to three optional 3-pole 125A subfeed breakers. The IAC-D is housed in a single, free-standing
cabinet designed for line-up-and-match installation, but may be installed separate from the UPS cabinet. The
recommended installation location for an adjacent IAC-D is to the left of the UPS cabinet.
1.2.4 Sidecar Integrated Accessory Cabinet-Bypass
A Sidecar Integrated Accessory Cabinet-Bypass (SIAC-B) provides maintenance bypass functions. The SIAC-B
is available in a three breaker configuration enabling power to completely bypass the UPS. The UPS can then
be safely serviced or replaced without interrupting power to critical systems. A four breaker configuration is
available to provide a convenient method for removing power from the UPS when using the maintenance
bypass to supply the load. The SIAC-B is housed in a single cabinet designed to be attached directly to the
UPS cabinet. The SIAC-B can be ordered for installation on the left side or the right side of the UPS cabinet to
assist in integration with the overall system.
1.2.5 Integrated Transformer Cabinet
An single transformer Integrated Transformer Cabinet (ITC) provides three-phase 480 Vac input to three-phase
208Y/120 Vac output voltage transformation and isolation for input to the Eaton 9E UPS. An optional Dual
transformer ITC adds three-phase 208 Vac input to three-phase 480Y/277 Vac output voltage transformation
and isolation for output to the critical load. The ITC is housed in a single, free-standing cabinet designed for
line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended
installation location for an adjacent ITC is to the left of the UPS cabinet.
1.2.6 Integrated Accessory Cabinet-Tie
An Integrated Accessory Cabinet-Tie (IAC-T) provides the ability to parallel up to four UPSs together for
increased capacity and/or redundant capability. The IAC-T is housed in a single, free-standing cabinet designed
for line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended
installation location for an adjacent IAC-T is to the left of the UPS cabinet.
1.2.7 Integrated Accessory Cabinet-Tie and Bypass
An Integrated Accessory Cabinet-Tie and Bypass (IAC-TB) provides the ability to parallel two UPSs together for
increased capacity and/or redundant capability. In addition, maintenance bypass functions enable power to
completely bypass the UPS power module. The IAC-T is housed in a single, free-standing cabinet designed for
line-up-and-match installation, but may be installed separate from the UPS cabinet. The recommended
installation location for an adjacent IAC-T is to the left of the UPS cabinet.
